Incinerators & thermal oxidizers

Thermal oxidation is the most flexible, efficient, reliable and in some cases the only means of destroying hazardous and toxic chemical wastes. For more than six decades, Linde Engineering has supplied thermal oxidation and incineration systems, specializing in liquid and fume incineration of hazardous chemical wastes. Our scope of supply includes oxidizers, heat recovery, by-product recovery and other equipment and controls to meet emission requirements.

Our incinerators provide emission solutions in the following industries:

Pharmaceutical

Chemical

Refining

Paper

Printing

Plant producers and users

Textile manufacturing and printing

Plastics and Olefins

Metals

Destruction of chemical weapons and munitions

Some of our processes can be used to recover acids, energy, metals and salts.

Flameless thermal oxidizers

Linde Engineering’s patented THERMATRIX® flameless thermal oxidizers (FTOs) are field-proven, high performance and cost-effective solutions for the destruction and removal of a wide range of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs). We offer a full range of FTOs to handle flows from 1 to 100,000 scfm (1 - 160,700 Nm³/hr). Our portfolio ranges from stand-alone emissions control devices to large-scale process treatment systems and process-integrated, turnkey pollution control systems.

Incinerators for gaseous and non-aqueous liquid wastes

Backed by over 60 years of experience, our flame-based oxidizers can dispose of every kind of organic gaseous and liquid waste generated by the chemical, petrochemical, pharmaceutical and metals industries. All of our systems are based on the high mixing performance generated by a high-swirl burner, effectively combining the combustible waste particles and the required combustion air, to ensure complete combustion.

We use simple up-fired designs if waste constituents are basically organic compounds. If halogens, sulfur and phosphorous are present, we incorporate scrubbers or other mist removal systems. We add particulate removal devices for waste that contains metals.

Incinerators for aqueous waste streams

Incineration is used to treat aqueous waste streams when biological processes are not a technically or economically viable option. Incinerating waste streams comprising salt brines, aqueous liquids with organic contaminates, inorganic salts or metals pose many challenges. The most important consideration is that organic components have to be completely destroyed.

Typical applications include:

Spent caustic from ethylene plants

Refinery waste

Pharmaceutical plant waste

Agricultural chemical plant waste

Bio-diesel plant waste

During the incineration process, most of the alkaline metals form molten salts that are corrosive to and reactive with many common materials. We meet the application challenges of these complex wastes by down firing the incinerator into our proprietary Sub-X® design to continuously remove salts from the incinerator walls. Our design rapidly cools the gases to deliver a highly efficient solution The high level of agitation dissolves most of the salt, ensuring that the gases undergo initial cleaning. Any residual salts within the gas stream are scrubbed, meeting the highest air quality standards.
